ADOT increases use of remote technology to ease traffic flow

State transportation officials are increasing their use of remote technology to help keep traffic moving on portions of highways that pass through various communities across Arizona.

The Department of Transportation says it has installed a wireless communication system that allows technicians in Phoenix to monitor conditions on State Route 347 in Maricopa and to adjust signal timing accordingly.

ADOT says similar systems are used to remotely monitor traffic signals in Nogales, in Tucson and in the Phoenix area and that a system is also planned for Safford.

The Maricopa system has infrared and video cameras at highway intersections and the capability to monitor traffic times and notify technicians about delays.

ADOT says University of Arizona researchers are to evaluate whether the system is cost-effective.
